At the moment the label has the format : 690.15:38 which is the shorthand for Days.Hours:Mins which can be a bit difficult to read. preferably I would like it to read: 690 Days, 15 Hours, 38 Mins or even 690d, 15h, 38m. I have tried looking into this but I cannot determine if this is possible or not.

The field itself is a measure and it is number formatted with the Duration format pattern: "h:mm:ss"
